Question

52 is 0.4% of what number? Use pencil and paper. Would you expect the answer to be a lot less than 52, slightly less than

52, slightly greater than 52, or a lot greater than 52? Explain.

Answer 1

52 is 0.4% of 130. You would expect the number to be a lot greater than 52

Explanation:

If the number we are trying to find is x, we have to use the equation x*0.4=52 which can be rewritten as 52/0.4=x

If you solve that, you get 130.

The number is expected to be a lot greater than 52 because 0.4 is almost 0.5 and that would mean doubling 52 so the number would be almost double 52. That means it would be a lot greater.

Answer 2

a lot less because 0.4 is not fully of 100%
